Imported DXF Model(173 Domains)

Automatically Defined Domains& Generated Meshes

FEA provides automatic defining & meshing function which defines mesh-able domains from curves (without creating surfaces) and then generates meshes for each domain.

Automatic defining & meshing function is very useful for complex 2D models which were originally modeled in AutoCAD.

Mesh Generation


29

Automatic Solid Meshing

FEA’s Tetra Mesher auto-generates tetrahedral solid mesh with variable sizes in smooth transition. (200,000 Tetra’s/min)

FEA’s Tetra Mesher is capable of including holes, curves and points that are present in/on solids.

Hybrid Meshing

FEA is under implementation of H-Morph Meshing to generate Hexa-dominant mesh.

H-Morph is a method to generate boundary conforming, hexa-dominant mesh for arbitrary solid geometries. (FEA uses Q-Morph and H-Morph algorithms proposed by S.Owen.)

FEA will also provide Prism Layer Meshing function. (Outer:Prism – Inner:Tetra)

33

Sub-mapped Meshing

FEA is under implementation of Sub-mappedMeshing functions for pseudo-Cartesiangeometries.

FEA adopts Volume Sub-mapping algorithms proposed by D.White and M.Whiteley.

Volume Sub-mapping is enhanced 3D mapping technique which sub-divides geometry into volume mappable sub-regions.

Pseudo-Cartesian shapes have interior and exterior angles that are close to π/2.
